Application filed. May 20, 1915. Serial No. 29,379.

To all whom it may concern:

Be it known that I, WILLIAM P. ROU- LAND, a citizen of the UnitedStates, residing at Decatur, in the county of Macon and State ofIllinois, have invented certain new and useful Improvements inDetachable Horseshce-Calksg and I do declare the fol lowing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and'use thesame.

This invention relates to improvements in horseshoes and more able calkstherefor.

.The object of the invention is to provide simply constructed andreadily applicable detachable heel and toe calks-which are designed foruse on shoes having stub heel and toe calks to which these detachablecalks are readily attached.

With this and other objects in view, the invention consists of certainnovel features of construction and the combination and arrangement ofparts as willbe' more fully described and claimed.

I In the accompanying drawings: Figure 1 represents a bottom plan'vlewof a horse-- shoe equipped with these improved calks; F ig 2 is asideelevation thereof; Fig. 3 is a transverse section taken on the line3-3 of Fig. 1; Fig. 4 is a detail perspective view of the heel calksshown in Figs. 1 to 3. Fig. 5 is a similar view showing a blunt heelcalk of similar construction.

In the embodiment illustrated a horseshoe 1 is shown of ordinaryconstruction to which is integrally secured at the toe and heel thereofextension or stub calks- 2 and 3 respeotive ly. The stub calk or toeextension 2 comprises an approximately rectangular solid member havinglongitudinally spaced apertures as 4 for the passage of fastening bolts5 for securing a removable toe calk 6 thereto. This calk 6 correspondsin length to the length of the stub calk 2 and is pro vided with atapered or sharpened surface engaging portion 7. The incline of thefront or outer face 8 of the calk 6 is very gradual or slow while theinner face 9 thereof is inclined abruptly and its inner or upper end isoffset from the body portion of the calk by a shoulder 10 whereby theinner or up or portion of the calk is rendered much th-ic er than itslower portion. The thicker upper portion of this calk' '6 is bifurcatedto proparticularly t6 detach-- the socket 11 and vide a longitudinallyextending socket 11 here shown open at both ends and which is designedto receive the stub calk 2. The furcations or arms 11" are, of the samelength and correspond in length to the width of the stub calk 2 so thatwhen said calk 6 is applied the edges of these arms or furcations 11which form the walls of the socket 11 will abut the lower face of theshoe 1 and thus be positioned to receive the ggeatest weight brought tobear upon the s co.

The armsll form the opposed walls, of

ing screw threaded apertures 12 positioned to register with theapertures t in the calk 2 when the parts are assembled to receive thefastening bolts 5 and whereby said detachable calk 6 is firmly andreliably clamped 1n operative position. I From the above description itwill be obvious that this toe calk 6 may be readily applied or removedwhile the shoe is on the horses hoof by means of the securing bolts 5which may be engaged or disengaged with very little trouble and in avery few minutes. Detachableheel calks 14 either sharpened as shown inFigs. 2 and-4 or blunt as shown in Fig. 5, are removably secured to thefixed stub'heel calks 3. Each calk 14 is formed integrally with thelower end of a U-sliaped attaching member 15, whose one arm 16 is ofgreater height than its other arm 18. The calks 3 are received snuglybetween the arms 16 and 18, the latter being disposed in contact withthe front sides of said calks and rising into contact with the arms ofthe shoe 1, while said arms16 conness and bent forwardly at 17 aroundthe rounded upper corners at the rear ends of said arms of the shoe. ,Bythis construction, all upward and downward movement of the members 15and calks carried thereby is pre-' vented. However, the arms of saidmembers are provided with registering apertures 19 which register withsimilar apertures in the stub calks 3 to receive bolts 20 which preventlateral movement of the members 15 and their calks.

In the form shown in Figs. 1 to 4, the calks are substantiallytriangular with their wider portions or bases joined to the'members 15and their vertexes 21 extending are provided with registerdownwardly toform surface engaging elements whereby the calks are reliably engagedwith ice and snow to prevent slippingl v used they are designed merelyto properly position the heel of theshoe in relation to the front or toewhich is equipped with the toe calks 6 and these oe calks 6 are dependedon for preventing slipping.

I claim as my invention: In combination with one arm of a horseshoe,said arm having its rear end bent downwardly to form an upright call:and having its upper rear edge rounded, a one piece U-shaped oalkattaching member snugly receiving said calk between its parallel arms,one arm of said member contacting with the gfront side of said calk andalso with the under side of the arm of the shoe to prevent verticalmovement of ing only toprevent 'lateralmovement of said attachingmember, and a second calk formed integrally with and depending from thelower end of said member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM P. ROULAND.
